When trying to add an existing "NextGEN Gallery" to a page, I can click the "Add NextGEN Gallery" button and the window comes up that allows you to select the gallery to add.
Clicking "Select or enter gallery" within the Gallery tab, "Select or enter album" in the Album tab, or "Select or enter picture" in the picture ,the swirling circle comes up, starts circling but nothing happens.
For those who don't uderstand what I mean, have a look at the instruction video:
My Problem is @ 2:50, where I can't select one( swirling circle comes up)
NextGEN Gallery version is 1.9.7
Thanks for help!
